Prepare for the Exam
Download the CHSOS Examination Blueprint (pdf), the basis for all exam questions.
Examination Preparation References (pdf) is a list of references to help you prepare for the examination. This is a partial list of items used as references for writing the items on the examination.
A short practice examination has been written by the same individuals who wrote the CHSOS exams. It is a short 30 question exam that is mapped to the same large domains as the full exam. After you have taken this test, you can go and see which questions you answered correctly and which ones you did not. In addition, each item has had rationales written to help you gain insight into why answers are correct. This is a great tool! There is a $75 (USD) charge to take the practice exam, and it remains available to you for 30 days after you sign up to take it.
